A score of 3 or higher → high risk - DVT prevalence of 17-53% → patients should receive an ultrasound[4]

Management

The distinction between distal and proximal relates to veins below and above the knee respectively.[5] Patients with superficial venous thromboses such as the long saphenous and short saphenous are at risk of developing a DVT, especially in patients who have a history of prior DVT although management with anticoagulation is controversial.[6]
